Feature/map search update

[edbrett]

Overview

Have you ever wanted to find yourself? Find something more? Well, if yourself is either a GFW map layer OR a location that is defined within the GADM36 political boundaries then have we got the search for you! So how can you use this deep, soulful search to find you:

• Search by dataset or location and a list of layers and locations appear based on escaped (by [comma], [space] and [comma][space]). You can add these to the map by clicking them.
• Search by coordinates
• Search by decimal degrees
• Search by UTM coordinates.

BONUS fixes:

• css fixes for position of analysis loader
• tidy up map v2 page code which was doing nothing special, just free loading.
